Back in the 70's I read a series of books featuring an enhanced man that was on the run from mysterious greatly enhanced agents. the enhancement was via implants for the hero whereas the agents had cybernetic augmentation of the skeleton and musculoskeletal system hence their greater power. the hero and the agents were created by the same agency and his augmentation may have been a development stage.
When the hero was near an enhanced he could power up using their energy against them. One example was pushing an enhanced out of a tower block window and riding the agent down to the ground where the agent's legs pistoned through his torso, but the hero was alive.
